LM95221 Datasheet (National Semiconductor) - Dual Remote Diode Digital Temperature Sensor

LM95221, Dual Remote Diode Digital Temperature Sensor

The LM95221 is a dual remote diode temperature sensor in an 8-lead MSOP package.

The 2-wire serial interface of the LM95221 is compatible with SMBus 2.0.

The LM95221 can sense three temperature zones, it can measure the temperature of its own die as well as two diode connected transistors.
